Hardware¶
Known board issues¶
- Lower Ethernet jack on the two-jack one should have its pins reversed, and seems to have incorrect connections anyway.
-Fixed on second schematic and board revision - Transistor controlling relay has drain and source switched.
-Fixed on second board and schematic revision - Ground may be disconnected in some places? There are air wires.
-No ground air wires found, all airwires solved on second board revision - Maybe the case should be connected to only one of the grounds, not both.
-Currently case is connected to AC ground

JP1: | ISP Programmer |
JP2: | Keyswitch, nonpolar |
JP3: | Backup relay power, Pin with line is + (closer to JP6) |
JP4: | Bus connection in |
JP5: | Top-Cardbox connection; Bottom-Bus connection Out |
JP6: | AUX pins: 5V-PA2-PA0-GND (GND closest to JP3) |
JP7: | AGND-AUX2 Jumper, pin closer to RJ45 jack is AUX2 |
JP8: | AVCC-AUX1 Jumper, pin closer to RJ45 jack is AUX1 |
JP3 caution:
- Use with keyswitch if MCU is dysfunctional and/or ToolBox is offline.
- Do not use if ToolBox is connected to other units via ethernet.
